AUTOMATIC SAFETY-PIN.

Specification of Letters Patent.

Patented May 14., 1907.

Application filed July 17,1905. Serial No. 270.126.

To all whom, it may concern.-

Be it known that 1, WILLIAM OoYLE, a subject of His Majesty the King of the United Kingdom of Great Britain and Ireland, a resident of Devonport, near the city of Auckland, in the Provincial District of Auckland and Colony of New Zealand, retired captain imperial service, have invented a new and useful Automatic Safety-Pin, of which the following is a specification.

The invention relates to safety pins, and more particularly to the class of safety pins which are automatically closed when the same is pushed into the material.

The primary object of the invention is the provision of a safety pin having automatic action through the medium of a slide for en gagement with a pin controlled by the movement of the said slide.

Another object of the invention is the provision of means for causing the closing of a safety pin when being manipulated by the operator.

Another object of the invention is the provision of means for automatically closing a safety pin whichis simple in construction, efficient in operation, durable, and inexpensive in the manufacture.

With these and other objects in view the invention, for example, is preferably executed by the construction, combination and arrangement of parts aswill be hereinafter referred to and as embodied in the accompanying drawings which disclose the preferred forms of the invention, however, changes, variations and modifications may be made as come properly within the scope of the claims hereunto appended without de- In the drawings t-Figure 1 is a side elevation of the invention showing the safety pin in open position; Fig. 2 is a slightly modified form of the invention in side elevation'and showing the safety pin in open position; Figs. 3, 4, 5 and 6 are still further modifications in side elevation showing the safety pin in open position; Fig. 7 is another modification in elevation showing the safety pin in a closed position; and Fig. 8 is a view in side elevation of the safety pin constructed as shown in Fig. 2, and the same fastened to a piece of material.

Similar reference. characters indicate corresponding parts throughout the several views.

In the drawings the safety pin is constructed of two parts, each formed of a single piece of material, andthe body as A and the slide as B forms the safety pin proper throughout the several views. The body as A comprises a strand of wire bent on itself to form a coil F, one end terminating in a point as P of a pin as O. Intermediate the point P and the coil F the strand of wire is' bent on itself to form a loop portion as E and an off-set as D, the latter being adjacent to the loop portion. The other terminal of the body A is bent on itself to form an eye as G which is engaged by a loop as J, which is produced by bending a strand of wire forming the body of the slide as B. The wire forming the slide B is further bent outwardly and inwardly, the bent portions being in alinement and in parallelism to form a guard K in which the pin O has free movement. The terminal beyond the loop J of the slide B is coiled, the convolutes of which lie contiguous to form a catch as H, with which engages the'jpoint P of the pin O when the safety pin has been brought to a closed position. The other or opposite end of the slide B is bent as at M to engage partly around the loop portion E of the body A. When the safety pin is manipulated by the operator the point P of the pin O is passed through a piece of material so that the point P protrudes therefrom, and by forcing the pin O further into the material the latter is brought against the guard K, moving the same on the pin C until it passes into the offset D and during the movement the catch H has been brought to engagement with the point P of the pin O, thereby locking the safety pin in a closed position.

In- Fig. 2 the pin O is bent on itself, the bent portions thereof being arranged in parallelism and contacting with each other and welded or otherwise brazed to form a solid projecting portion E. With this exception the construction of the safety pin is identical with that as shown in Fig. 1.

In Fig. 3 the body portion A is bent on itself to form an elongated eye or loop portion guide-way, and

is freely movable therein. The said body A is further bent to form an off-set D in proximity to the pin portion C thereof. l/Vith these exceptions the coilstruction of the safety pin and the operation tlz hereof is the same as the structure shown in In Fig. 4 the construction of the safety pin is the same as that-shown in Fig. 3, with the exception that the body A is bent on itself as at F in lieu of a coil.

In Fig. 5 the body A at one terminal there of is bent on itself to form an eye J and through the opening formed thereby passes the bent portion G of the slide B intermediate the terminals of the latter. Said slide B beyond the bent portion G terminating in a coil forming a catch as H. With these exceptions the construction of the safety pin is the same as that shown in Fig. 3.

In Fig. 6 the body A intermediate the coil F and the end having the eye G is bent on itself to form a loop E the latter being in proximity to the coil F and forming a guide for the bent end. as M of the said slide B.

In Fig. 7 is shown a lug as R on the slide B intermediate the terminal M and the guard K to form a grip member which may be grasped by the operator to release the safety pin from closed position by the disengagement of the pin 0 from the catch H. F urtherrnore, in this view the eye G formed in the body A is shown on the reverse side thereof from that shown in Figs. 1, 2, 3, 4 and 6. In the said Fig. 7 is shown the safety pin in a closed position.

In Fig. 8 is shown the safety pin as disclosed by Figs. 2 and 7 applied to a piece of material, the same being in a closed position.

It will be apparent that the loop portions E, E or guide-way E cause the catch member H and H to be brought in position for engagement with the point P of the pin C when the safety pin is in the act of being illserted into a piece of material, and that when the point P of the pin C has been inserted a suitable distance into the material the latter is brought into contact with the guard K forcing the same in a direction over the pin 0 within the off-sets D or D, and when the said guard is in engagement with the off-sets the point P of the pin C is in engagement with the catch II or H and will overcome any liability of accidental displacement of the body A and the slide B with respect to each other,

thus holding the tion.

Having described the invention what I claim is 1. An automatic safety pin involving a body having a pin terminating in a point, a slide connected to the free end of said body and having a catch for engagement with the point, a guide on the body portion for actuating the pin to bring the point into engagement withthe catch, and an off-set to maintain the slide in a locked position.

2. An automatic safety pin. comprising a body having an oil-set and apin, a. slide associated with the body and having a catch for engagement with the pin, and means for guiding the body and, slide when the latter is being actuated to bring the pin into locking engagement with the catch.

3. In an automatic safety pin, a body formed of a single piece of material, a slide formed of a single piece of material, said body having an off-set and a pin, said slide having a catch at one end, and means associated with the body and cooperative with the slide to form a guide for causing the said catch to be brought into engagement with the pin during the closing action of the safety. pin.

4. An automatic safety pin involving a body having a pin terminating in a point, a. slide associated with thefree end of said body and having a catch at one end for engagement with the point of the pin, a. guide formed in the body to bring the catch in operative position with respect to the point of the pin, an off-set in the body, and means formed in the slide for engagement with the off-set to lock the said slide in a closed position.

5. An automatic safety pin comprising a body portion bent on itself to provide a loop and having a pointed terminal, a slide asso ciated with the opposite free terminal of the body and having a catch for locking engagement with the pointed terminal of the body, an off-set in the body, and a guard for engagement with the off-set to hold the body and slide in a locked position with respect to each other when the pin and catch are in engagement.
